Lenders underwrite spec shells on absorption, and absorption depends on how fast a prospect can picture a truck backing into the building. We build for industrial developers, REITs and institutional owners who need a design that tours well, prices cleanly and leases without a six-month tenant improvement fight. The metrics we track with them are the ones in their pro forma: clear height, dock-door ratio, truck court depth, trailer stalls, column spacing and cost per square foot.
A developer is also a capital partner, so the contractor has to respect the draw schedule. Land closes, entitlements finish, a construction loan funds and the clock on interest starts. We build schedules that show lender-friendly milestones: grading complete, panels up, roof dry, slab placed, shell complete and certificate in hand. At each milestone we report quantities and costs in the format the owner's asset manager already uses.
Our two main programs are the spec warehouse shell for the open market and the build-to-suit warehouse when a tenant signs before ground is broken.
Multi-Building Parks Are Becoming the Norm
Colorado developers build parks, not one-off boxes. The Front Range has several concrete examples. A national industrial developer bought 35.6 acres at East 152nd Avenue and Washington Street in Thornton in September 2023 for 25 Commerce Park, a three-building, 453,550 square foot industrial project. Commerce Yards at 96th Avenue and Heinz Way in Commerce City is a 466,000 square foot, three-building project with rail access in an Enterprise Zone, financed with $77.1 million, with construction set for April 2026 through May 2027.
South of Denver, the town council in Monument unanimously approved two industrial distribution warehouses in phase 2 of the Falcon Commerce Center on January 14, 2025. A 2018 study examined a rail-served industrial park on roughly 3,000 acres of Christian Ranch south of Fountain, with more than 2,500 acres proposed for industrial use. The common thread is phasing: developers entitle the park, then deliver buildings as leasing allows.
Pro Forma Line Items We Pin Down Early
We help developers fix the numbers that move yield. Site work, including mass grading, retaining walls, utilities and detention, can take a large share of hard cost on a sloping or constrained parcel, and it comes before any revenue-producing square foot exists. Next are tilt panel and roof structure, which respond to clear height and column spacing, and then paving, which responds to trailer stall count.
The design choices that save money without hurting leasing are modest: standard bay sizes, repeatable dock packages, a uniform slab spec and a shell office that can grow. We also show the price of future-proofing items, such as extra power, a heavier slab or knockout dock panels, so the developer can decide what the market will pay for. A package option for tenant improvement allowances keeps the first lease from stalling.
Preconstruction That Fits the Capital Stack
We start with the parcel and the entitlements, then test fit two or three building sizes against site constraints. A plan that works on paper can lose a bay to a utility easement or a detention pond, and the loss falls straight into absorption. We run those test fits with real civil constraints so the developer buys land with a building count in mind.
From there we offer a guaranteed maximum price or a negotiated price, pegged to a design package that the lender accepts. Contingency, allowances and exclusions are stated plainly. The developer's team sees the same estimate we see, and we update it as the design matures instead of presenting a new number at the end.
Entitlement and Permit Risk Across Jurisdictions
A developer working in several cities sees code editions that differ by jurisdiction. The Home Builders Association of Metro Denver tracker dated January 20, 2026 shows Adams County, Arvada and Castle Rock on the 2018 I-codes, Aurora and Arapahoe County on 2021, and Boulder, Golden and Cherry Hills Village on 2024. The tracker is a trade source rather than an official one, so we verify with each department before locking a design package.
Energy code adds a second layer. Under HB22-1362, any county or city updating its building code on or after July 1, 2023 must adopt an energy code with equivalent or better performance than the 2021 IECC, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. We carry that through the envelope, roof, lighting and solar-ready details of the shell, which affects both the permit and the tenant's operating cost.
Schedule to the Loan, the Lease and the Weather
Developers measure schedule by interest carry and by lease commencement. We build the baseline from land closing through site permit, grading, vertical and turnover, and show float where the weather can bite. Winter pours need protection, spring runoff softens subgrades, and summer storms cut crane days. We price those days and give the owner a range, not a single optimistic date.
When a tenant signs early, we hold a fast-track plan: early foundation packages, parallel panel casting and phased permits. It costs more than a standard sequence, but it can pull a lease start forward by weeks and the rent on those weeks often covers the premium.
Product Types for the Developer's Menu
Most park programs mix building types. A distribution center serves large tenants with high clear heights and deep truck courts, and a flex or light industrial building serves smaller tenants who want office, a few doors and shallow bays. Many developers pair a big-box building with a rear-load flex building in the same park to capture two tenant pools.
We also help owners decide when to build cold-ready or food-grade space on speculation. A cold-ready shell carries extra power, a heavier slab and space for panel upgrades, which makes it more valuable to a food tenant, but it should be offered only where tenant demand supports it.
Walk the Parcel With Us
Send the parcel, the entitlement status and your target clear height, and we will return test fits, a cost range and a schedule that works with your loan.
Common Questions
What should a spec warehouse shell include to lease quickly?
Modern clear height for the submarket, a healthy dock-door ratio, good trailer parking, ESFR-ready sprinkler infrastructure, ample power and a shell office that can be finished by the tenant. The mix varies by submarket, and we benchmark against competing buildings with your broker.
Can you work with our civil engineer and architect already under contract?
Yes. We join the team as constructor, review the design for cost and constructability and propose value engineering that does not cut leasing appeal. We can also take on design-build if you prefer one party responsible.
How do you manage tenant improvements in a shell building?
We build the shell to a standard, then price tenant improvements by menu: demising, office finish, racking-ready slab upgrades and dock additions. Pricing is ready before the lease is, which helps brokers close tenants, including logistics and 3PL operators.
What happens if a cold chain tenant appears after we build?
That is a real scenario. We can convert part of a dry shell if the slab, power and structure were planned for it, as we describe for cold chain and food customers. Otherwise a build-to-suit expansion bay is cleaner.
How do you report progress to lenders?
We provide monthly pay applications with a schedule of values tied to the milestones above, plus photos, lien waivers and an updated cost-to-complete forecast, formatted for the lender's inspector.
